METALLIC COMPOUND.

No Drawing. Original application filed June 7,1915, Serial No. 32,608.

July 29, 1916. Serial No. 112,006.

To all whom it may concern:

Be it known that I, HERBERT B. COHO, citizen of the United States, residing at Mount Vernon, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Metallic Compounds, of which the following is a specification.

My invention relates to compounds in Which the basic elements are lead and copper alloy and tin held sulfid of antimony, and is a division of my application for patent Serial No. 32,608, filed June 7th, 1915. I

The object of my invention is to produce a compound of the character'described that may be readily commingled, economically produced and which will result in a metallic compound that is susceptible of varied and extensive utility. Another object thereof is to produce an alloy of lead and copper com-- mlngled With sulfid of antimony and tin resulting in a compound that may be successfully employed as a substitute for Babbitt-metal with advantageous results. And a still further object of'my invention is to produce a metallic compound of the character described in which the fluidity .of the mixture is greatly increased to render same capable of being cast into small articles.

To these ends my invention includes the combination and arrangement of component 1ngredients to be hereinafter described and more particularly pointed out in the claim.

In the preparation of my compound I employ variedpercentages of lead, copper, sulfid of antimony and tin, the various pro portions being determined by the hardness of the resultant compound described. I preferably employ needles antimony (sulfid) because it is readily obtainable "in that form, but it Will be understood that any Specification of Letters Patent.

in suspension With Patented FebJZY, 1917. Divided and this application filed compound of antimony and sulfur that is suitable for the purposes of my invention may be used.

.The exactproportions of lead and copper used are determined by the specific result desired, and may be varied wlthin a Wide range. For some purposes, nine parts of lead may be employed with one part of 0013- per, While in other instances, nine parts of copper and one part of lead is preferred. The proportions of antimony sulfid employed is regulated by the degree of hardness desired, as'in a mixture of fifty pounds of copper and fifty pounds of lead from five pounds to twenty-five pounds of sulfid of antlmony may be used.

The quantity of tin to be employed is llkewise regulated by the results that are desired to beat-tamed. Thus, from one to nine parts of my compound may be of tin, by the addition is desired to increase the fluidity of the fused compound tofacilitate its casting into small articles, a small quantity of sodium I claim as new and desire to be secured by Letters Patent, is:

A metallic compound, comprising lead and copper commingled and fused with sul fid of antimony associated With sodium,

substantially as described.

In testimony whereof I hereby afiix my signature. I

HERBERT B. COHO.

of Which the resultant com pound 1s rendered susceptible for successful employment as a satisfactorysubstitute may be incorporated therewith as a flux in the preparation thereof. Having thus described my invention, What
